Hi.

How can i find the drag coefficient of a body with ANSYS CFX?

Thanks.

You can integrate pressure field and shear stress field over the body surface (CFX-POST). If the integration is in the parallel direction to the flow you got drag force. If the integration is in the normal direction, instead, you got lift force.

Hi,

A better way is to use the force_x/y/z functions as that calculates the total force on the surface. These can be called as a CEL expression as the simulation progresses or done in post-processing in CFX-Post.
